The total of native bee types in Europe facing extinction has more than doubled over the past decade, while the count of threatened butterfly types has close to doubled.
This pressing issue for crucial pollinating insects was revealed by scientific studies for the red list of threatened species, which found that at least 172 bee species out of over 1900 were at risk of extinction in the European continent.
The total of butterflies facing extinction in Europe has risen from over thirty-five to 65 since the earlier research, conducted 14 years ago. One species, the Madeiran large white butterfly (Pieris wollastoni) has now been declared extinct.
In addition to their aesthetic appeal and cultural significance, pollinators like bees and butterflies are essential supports for our well-being, our food supplies and our economies – supporting the fruits, vegetables and seeds that feed us,” stated Grethel Aguilar. “The latest European red list assessments reveal serious challenges, with dangers increasing for butterfly types and crucial wild bee types.”
The reasons of the swift recent drops are the continuing harm or degradation of natural habitats caused by intensive agriculture and land abandonment, draining wetlands, livestock overgrazing, and the utilization of chemical fertilisers and pesticides including neonicotinoids. The division of environments suitable for pollinators substantially boosts the risk of local extinctions.
Climate change is also demonstrated to be a primary risk: Over half of all at-risk butterfly species in the European continent are endangered by the climate change crisis – approximately twice as many as a decade ago.
Nearly nine out of ten of plants that flower in European nations rely on insect pollination, according to the lead coordinator of the wild bee assessment. “Regrettably, wild bee groups are in severe drop and cannot be easily replaced by managed bee colonies,” he said. “If non-managed bees vanish, many wild plants might be threatened too – of which flower-rich meadows and attractive orchid varieties are just a few examples.”
15 varieties of bumblebee types, which have an essential part in fertilizing peas, beans, peanuts and clover, and 14 species of cellophane bee species, known for fertilizing trees such as willow trees and red maples, are now classified as threatened. Simpanurgus phyllopodus, a mining bee type unique to the mainland and the single type of this biological genus in European nations, is now evaluated as severely threatened – the scientific category most akin to disappearance in the wild.
Butterfly species that are only found on mountain peaks are highly susceptible to global heating as they need to move uphill as their environments become hotter but ultimately have no room left. In the southern part of Spain, the grayling of Nevada and the Andalusian anomalous blue are among above 40 percent of European endemics (solely present in Europe) at risk of extinction.
In the Mediterranean, varieties such as the critically endangered Karpathos grayling butterfly are imperilled by extreme wildfires and drought.
Meanwhile, in the Far North, global heating is causing the forest boundary to advance northwards by many meters each year, with bushes encroaching on bog and tundra. Higher temperatures also mean caribou can not anymore cross the ice to graze Arctic meadows and prevent them from overgrowing. Eight butterfly species are at risk of extinction in this zone, including the fritillary of Freyja and the Arctic ringlet.
“The largest habitat for all these pollinating insects is grassland rich in flowers and that is vanishing rapidly across the European continent because of all these elements,” said a lead coordinator for the butterfly assessment. “The positive thing is that so many people are aware now and there’s a lot more understanding. Under the EU nature restoration legislation, all participating nations have to reverse the decrease in pollinating species by the year 2030, and they are going to have to initiate measures. There are property owners who are engaged. It is hoped they can obtain the encouragements that will support them on their way.”
As per Martin Warren, there is “readily achievable actions” in terms of measures for pollinators which won’t reduce agricultural output – and could improve it – such as agricultural producers creating flower-rich margins around their cultivated areas.
the EU’s environment commissioner, portrayed the conservation status of native bees, butterflies and additional pollinators as “dire”.
“Urgent and collective action is required to confront this danger. Along with participating nations, the EU Commission has put in place an EU-wide tracking system for pollinators based on the EU nature restoration regulation, which will assist in monitoring our progress. Now, we need to concentrate on execution and collaboration with member countries to protect our pollinating species,” she said.
The publication of the bee and butterfly assessments is subsequent to the initial European-wide assessment of hoverflies, another vital pollinator group. Published in 2022, it revealed that over one-third of all hoverfly types in Europe were threatened with extinction.
